disk drives are sold by decimal gigabytes, so "300GB" is 300,000,000,000
bytes.
software tends to use binary gigabytes, so 273GB is 273 * 1024 * 1024 *
1024, or 293,131,517,952 bytes, which is *about* 300GB (decimal)
btw, in an earlier email, I believe you said you had a HP
DL-something.... if that has an HP "SmartArray" hardware raid
controller, its quite likely using the 'cciss' driver (/dev/cciss/c0t0d0
..) and I'm not sure the previously-offered advise of cat "...." >
/proc/scsi/scsi is applicable.
